In a Facebook post on Monday, the General Staff of the Ukrainian Armed Forces said the Russian army lost 147 aircraft, 134 helicopters and 647 tanks.
At least 1,844 Russian armored vehicles, 330 artillery systems, 107 rocket launch rocket systems and 54 anti-aircraft warfare systems were destroyed across the war-torn country, it added.
Besides, Russian forces also lost 1,273 vehicles, seven ships and cutters, 76 fuel tanks and 92 drones, the statement said.
The Russian war against Ukraine, which started on Feb. 24, has been met with international outrage, with the European Union, US and UK among others implementing tough financial sanctions on Moscow.
